Description of problem:
I'm not sure what convention the UI is trying to follow, but it mixes title and sentence case throughout the UI.

In the dropdown menus off the tabs, everything is sentence case, so anything with more than one word, the second word is lowercase, yet many of those (not all) when you click on them and go to the page, the page title capitalizes the second word. This inconsistency follows through to the dialog windows as well, where some field titles with multiple words all start with a capital letter, others only the first word starts with a capital letter.

Title case = Discovered Hosts
Sentence case = Discovered hosts

Hosts > Operating systems leads you to a page titled 'Operating systems' (sentence case).
Hosts > Provisioning templates leads to a page titled 'Provisioning Templates' (title case).

Clicking the 'New Operating system' button brings you to a dialog, where the first tab is titled 'Operating Systems' (title case). The other tabs in that dialog are Installation media and Partition table (sentence case). In that tab, we have 'Major version', 'Minor version' (sentence case), and then 'OS Family' (title case).

There are many more instances of this, but those are a few examples to demonstrate what I'm talking about.

Title case is more common to use for UIs.
